Windows 95 Certificate Of Authenticity

[Wesley Godinez]

Nowwe need to implement Client Certificate Authentication. Currently i have enabled both Client Certificate Mapping Authentication and Windows Authentication, and configured the service to accept client certificate.Everything works good like this, but when i log in with Client Certificate, the process for windows authentication is skipped (I have checked this with Wireshark and I can see only SSL packages)

My intention is to make the website more secure if some user loses his certificate, so the lost certificate cannot be used for accessing the website by a person who has somehow obtained the lost certificate.

You would have to use Client Certificate Mapping Authentication,(AD integrated) and not IIS Client Certificate Mapping Authentication. Windows auth will grab users logged on credentials and pass them through. When you use IIS Client Certificate Mappting Authentication you are entering in a username and password. You would use basic auth for this.

Once again I'm hitting this community for some potential answers. I am attempting to setup 802.1x authentication using certificate on a "wired" Windows 10 host against Forescout as the RADIUS server. Forescout does not have great documentation on how this should be done on the Windows side. Currently, Meraki support verified that the Windows 10 test host I have is not sending 802.1x auth attempts and failing over to MAC address bypass directly.

I believe the above works, I am not clear regarding what settings should be on the Windows 10 host side, even with Forescout's professional service help. I have our internal CA's root cert loaded in Forescout, as well as on the Windows 10 host. Windows 10 host is configured with these settings under the Authentication tab of the Ethernet NIC:

I found the issues eventually myself. The endpoint test laptop did not have certificate meant for client/server authentication from our internal CA installed. Also our Forescout server did not have the intermediate certs from the subordinate CA servers. After that, I also found out that on the endpoint, I had to configure authentication to do "Computer authentication" only because user was getting tried and that's not what I want. THEN, I found out on the Forescout or RADIUS server, a different cert was getting hit. So I had to reconfigure the client end to use that cert instead. 802.1x EAP-TLS authentication then started working.

The most common issue I run into is that the windows service "Wired AutoConfig" has not been changed from "Manual" to "Automatic" startup. My guess is this is why you are not seeing the machine attempt to authenticate.

This is often normal due to how operating systems publish root certificates. You're likely seeing the overlap between one CA's root certificate as it expires and is "covered" by a new certificate by the same CA. Nonetheless, good for you for not trusting blindly.

Most public Certificate Authorities publish fingerprint information about their root certificates. You can hunt these down from CA to CA and verify the certificate you see in your root trust store matches the fingerprints they publish. For example, Thawte publishes to

Authenticity can be kind of checked if you search for the fingerprint online and find the certificate where you would expect it. But this is not foolproof because this might be a fake site which is just looking good and has a trustable host name. In any case you don't know the party personally and authenticity does not mean that the party can be trusted.

At the end you have to trust the vendor of your OS or browser that it is doing the right thing, because effectively you have no way to really verify it. But this kind of trust is not uncommon, i.e. you trust your supermarket that the food is edible and not expired or even poisoned, you trust your gas station that the gasoline is not dangerous for your car ... - i.e. you already trust others in security issues. And you hope that if this trust is no longer justified you will somehow be notified.

Trust can go wrong as can be seen in the Superfish affair where one trusted the vendor (Lenovo) to ship a trustable computer. But this computer contained a software to injects ads and additionally the software installed its own root certificate to man-in-the-middle connections in order to inject ads into https traffic too. This certificate was definitely authentic, but most people would not consider it trustable.

I have an issue in client based authentication for IOS devices. I have imported the client certificate in windows and android it works same cert installed in iphone it shows an error client certificate not found.

Recently, I have see behaviour of client certificate installation has changed in IOS 12. Client certificate should be deployed as VPN profile using MDM. If I deplot using MDM I'm not getting the supported format by IPhone.

By direct I can able to install certifcate as PKCS12 format but it shows an error client certificate not found. but through MDM I can able to install only it as CER format which I'm not sure the certificate is getting changed during the deployment and because of that it is not working.

Sorry @Venkatesan_radhakrishnan , I don't know all that much about iOS to be honest. The only experience I had was when I was testing the iOS integration for GP 5.0, and it was limited to what I previously provided in the thread you're likely referencing.

I am no longer part of this project but i do remember we had similar issues, the only workaround for us was to create the config file with apple configurator (including the user certs) on a MAC and then use InTune to push this out to the device.

Also advised to go for apple configurator to push certificate through config file. I have one more query assume like I have enterprise CA, Can I genertate rootCA and subordinate client certificate and import that certificate to Palo alto in PKCS12 format and import to IOS devices in CER format. Whether this will solve my issue.

Because Now, I have certificate CA self signed from palo alto and client certificate are signed by root CA in palo alto. I'm exporting this in PKCS12 format and coverting it to CER format and then pushing to device through MS intune MDM and facing client certificate not found issue.

To avoid this conversion of certificate if i export from my enterprise CA it will deliever PKCS12 format for PA and CER format for IOS devices so can avoid conversion but whether this will work? or private key for client certificate is must required ?

Auditing is the process whereby information about operating requests and the outcome of those requests are collected, stored, and distributed for the purposes of non-repudiation. In other words, auditing provides an electronic trail of computer activity. In the WebLogic Server security architecture, an Auditing provider is used to provide auditing services.

If configured, the WebLogic Security Framework will call through to an Auditing provider before and after security operations (such as authentication or authorization) have been performed, when changes to the domain configuration are made, or when management operations on any resources in the domain are invoked. The decision to audit a particular event is made by the Auditing provider itself and can be based on specific audit criteria and/or severity levels. The records containing the audit information may be written to output repositories such as an LDAP server, database, and a simple file.

Authentication is the mechanism by which callers prove that they are acting on behalf of specific users or systems. Authentication answers the question, "Who are you?" using credentials such as username/password combinations.

In WebLogic Server, Authentication providers are used to prove the identity of users or system processes. Authentication providers also remember, transport, and make identity information available to various components of a system (via subjects) when needed. During the authentication process, a Principal Validation provider provides additional security protections for the principals (users and groups) contained within the subject by signing and verifying the authenticity of those principals.

A principal is an identity assigned to a user or group as a result of authentication. Both users and groups can be used as principals by application servers such as WebLogic Server. The Java Authentication and Authorization Service (JAAS) requires that subjects be used as containers for authentication information, including principals.

As part of a successful authentication, principals are signed and stored in a subject for future use. A Principal Validation provider signs principals, and an Authentication provider's LoginModule actually stores the principals in the subject. Later, when a caller attempts to access a principal stored within a subject, a Principal Validation provider verifies that the principal has not been altered since it was signed, and the principal is returned to the caller (assuming all other security conditions are met).

Whether the client is an application, applet, Enterprise JavaBean (EJB), or servlet that requires authentication, WebLogic Server uses the Java Authentication and Authorization Service (JAAS) classes to reliably and securely authenticate to the client. JAAS implements a Java version of the Pluggable Authentication Module (PAM) framework, which permits applications to remain independent from underlying authentication technologies. Therefore, the PAM framework allows the use of new or updated authentication technologies without requiring modifications to your application.
